Figure 7 Database Design
The Flexible Input Data Base (FIDB) contains a list of all I/O parameters available for all aircraft within a fleet. The FIDB contains information regarding LRU source, data busses, labels, scaling, and resolution for each I/O parameter.
The Airline Modifiable Information (AMI) database is generated by the user to customize their AOC application. AOC screen and print formats, message definitions and trigger logic can all be specified in the AMI. Changes to the AMI only require a dataload operation but no certification activity. This is a significant change from pervious systems, such as our Mark II CMU and competitors CMUs, which still maintain much of this processing within an AOC software segment. With the Mark III CMU, all such functionality is contained within the AMI, providing airlines significantly more control and flexibility for performing changes, as requirements change.
The Honeywell Generated Information (HGI) database provides capability similar to the AMI, but for protected data typically used by ATC applications. Unlike the AMI, HGI changes require certification although no change to the embedded operational software.
